Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed larch 2, 1915. Serial No. 11,449.

To all whom it may concern:

Be it known that I, AUoUsrUs P. BEN- NETT, a citizen of the UnitedStates, and a resident of the boron h of Manhattan, city, county, andState 0 New York, have invented an Improvement in Sna -Fasteners, ofwhich the following description, in connection with the accompanyingdrawing is a specification, like letters on the drawing re resentinglike parts.

he present invention relates to an improvement in snap fasteners, theobject thereof bein to provide a noiseless fastener which ma e readilyassembled.

One em odiment of my invention is illustrated in the single figure ofthe drawing which represents the male element of a preferred form ofsnap fastener in central vertical section.

Referring to the drawing, 1 indicates a housing attachable to a iece offabric or other material 2 by suitab e fastening means, as prongs 3extending through registering slots in upper and lower plates 4 and 5respectively, located on opposite sides of the fabric. A stud portion 6ma be movably mounted in the said. housin to cooperate with a femalemember not i ustrated. This stud 6 ma be provided with a shank portion 7ada te to be retained by an inwardly turne flange 8 forminglthe up orportion of the housing 1, and wit a shoufder portion 11 to an age theunder side of said inwardly turned ange 8. The lower end of the stud 6may also have a peri heral groove 9 to engage and retain one en of ahelical spring 10, the other end of which bears against the base plate4, thus pressin the shoulder 11 yieldingly against the un or portion ofthe flange 8 and holding the stud 6 normally in its outermost position.

Copies of this patent may be obtained for iive cents each, by addressingthe The structure hereinabove described and embodying my improvement insnap fasteners, accomplishes a two-fold object. In the first place, thesprin pressed stud 6 is held firmly in contact wit the flange 11 and maybe depressed ordinarily only by positive pressure so that it is not freeto rattle against the said flan e. While this desirable result mightalso accomplished by providing spring pressure against the butt 0 thestud 6, there would be considerable delay in assembling the variousparts owing to the difiiculty of handling a. small detached spring. Toobviate thls, I have rovided in t e stud a eripheral groove 9 w ichretains one end 0 the spring thus simplifying the operation ofassembling and also preventing accidental dis lacement of the partsafter the structure is assembled.

I claim as my invention:

In a snap fastener, the combination of a housing having an inwardlyturned flange portion, a stud havin a shoulder portion to engage theunder side of said inwardly turned flange (portion, a sprin adapted topress said stu portion norma ly into contact with said inwardl turnedflange portion of the housing, and a peripheral groove in said studport1on adapted to return one end of said spring;

In testimony w ereof, I have signed my name to this specification, inthe presence of two subscribing witnesses, this 26th day of February1915.
